The invention concerns a laser positioning device generating a reference beam for positioning a subject or an object in the medical or industrial field, comprising: A) support and directing means (1, 3) connected to a fixed part (2) (wall, partition, ceiling); B) an optical assembly mounted pivoting on the support and directing means (1, 3) and comprising a laser source (50) formed by an infrared crystal laser and a frequency duplicator (507) to emit a green light, and in the laser source (50) output, means for reflecting the beam (51, 52) and a group of two mirrors (53, 54) series mounted in the beam, the first mirror (53) being semi-reflecting and each mirror (53, 54) in said group being followed by an optical system (57, 58) spreading the beams along two perpendicular fan-shaped directions.

Dispositif de positionnement à laser créant un faisceau de repère servant à positionner un sujet ou un objet dans le domaine médical ou industriel. Dispositif comprenant: A) un moyen de support et d'orientation (1, 3) relié à une partie fixe (2) (mur, cloison, plafond); B) un ensemble optique monté pivotant sur le moyen de support et d'orientation (1, 3) et comprenant une source laser (50) formée d'un cristal laser infrarouge et d'un doubleur de fréquence (507) pour émettre une lumière verte, et en sortie de la source laser (50), un moyen de renvoi du faisceau (51, 52) et un groupe de deux miroirs (53, 54) montés en série dans le faisceau, le premier miroir (53) étant semi-transparent et chaque miroir (53, 54) de ce groupe étant suivi chacun d'un système optique (57, 58) étalant les faisceaux suivant deux éventails perpendiculaires.
